COOKING RANGE OR STOVE.

SPECIFICATION forming part of Letters Patent' No. 578,690, dated March9, 1897.

Application filed April 7, 1896. Serial No. 586,507. (No model.)

To all whom it may concern:

Be it known that we, RICHARD J. BROCK- MEYER and JOSEPH A. BROCKMEYER,of the city of Baltimore and State of Maryland, have invented certainImprovements in Cooking Ranges or Stoves, of which the following is aspecification.

The object of this invention, in common with others of its class, is toconstruct a cooking stove or range in such manner that the oven thereofwill be heated from the door side, as well as from the other sidesthereof, as will hereinafter fully appear. With this in view we providethe stove-plate on the front or door side of the stove with twoopenings, one above and the other below the oven, and make the oven-doorhollow and provide the inner plate of the door with openings which, whenthe door is closed, register with the openings in the stove-plate beforementioned. Further, we hinge over the openings in the stove and'doorplates gravity-closing valves and place across the said openings spurswhich serve to open the valves as the oven-door is closed. The spacesabove and below the oven are then in communication with the interior ofthe door, and when the direct-draft damper of the stove is closed andthe products of combustion, which, from the construction of the stove,have a movement in a downward direction or from over the oven tounderneath the same, a portion of the said products pass downwardthrough the door and heat the inside plate thereof, which plateconstitutes the front wall of the oven.

In the further description of the said invention which follows referenceis made to the accompanying drawings, forming a part hereof, and inwhich- Figure l is an exterior front view of the improved cooking rangeor stove with the ovendoor open. Fig. 2 is a central longitudinalsection of the same. Fig. 3 is across-section of Fig. l, taken on thedotted line Qc.

Referring now to the drawings, A is the stove-oven, and a the spaceabove the oven, separated from the space b in the rear of the oven by aplate B, in which is situated the direct-draft damper C. The space cunder the oven is in communication with the space ZJ and also with thespace d at the end of the stove, which latter is separated from thespace b by a partition-plate D. The wall E of the oven is heated by there-brick e in the firepot F.

G is the oven-door, hinged, as is common, to the stove-plate H. Thisdoor is made hollow, so as to produce the space f, and the inner plateof the door is denoted by g.

I and J are openings in the stove-plate H, situated, respectively, aboveand below the oven, the former leading into the space a and the latterinto the space c. These openings have each a gravity-closing hingedvalve 7L, the valves being on the inside of the stoveplate H.

In the oven-door plate g are openings K and L, which register with thoseI and J in the stove-plate H when the door is closed, and these latteropenings having gravity-closing valves i, similar to the ones h,beforedescribed in connection with the stove-plate I-I.

Across each of the openings I, J, K, andL is a spur j, and' the spurspass each other as the oven-door is closed and open the valves.

When the direct-draft damper O is open, the products of combustion fromthe fire-pot take the shortest and most direct course to the stovepipe,and the oven is not heated except through the plates E and at the top;but when the said damper is closed the products of combustion have topass through the space a, over the plate 7c, down the space d at the endof the oven, along the space c under the oven, and thence upward throughthe space b at the back of the oven to the smoke-pipe M. Now as thegeneral direction of the products of combustion after leaving the plate7c is first downward some of them pass through the openings I and K intothe upper part of the space f in the Oven-door and out through the loweropenings J and L into the space c and mix with the remainder, which havetaken the direction described. From this description it will be seenthat the door-plate g is heated from products of combustion while takinga downward course through the ovendoor and that theoven receives heatfrom the door.

When the oven-door is opened, the valves h and close by gravity, as thespurs j no IOO longer serve to keep thern open and no air can enter thespaoef within the door or into the spaces around the oven.

We claim as our invention- In a Cooking range or stove, the frontstovevided with spurs which serve to open the valves as the oven-door isclosed, and thereby induce a downward current of `products of combustionthrough the hollow door, when the direct-draft damper is Closed,substantially as specified.
